Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 63% and getting smaller. The lunar cycle is 20 days old.

Moonrise and moonset

The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠22° of ♈ Aries tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 25 July 2059 at 02:24.

Buck Moon before 5 days

Next Full Moon is the Sturgeon Moon of August 2059 after 23 days on 23 August 2059 at 09:42.

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Apparent angular diameter ∠1956"

Lunar disc appears visually 3.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1956" and ∠1890".

Lunation 736 / 1689

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 736 of Meeus index or 1689 from Brown series.

Synodic month length 29.57 days

The length of this lunation is 29 days, 13 hours and 39 minutes and it is 1 hour and 44 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 55 minutes longer than the mean synodic month length. It is 6 hours and 8 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠119.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠119.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠149.3°.

Moon after perigee

3 days since point of perigee on 26 July 2059 at 20:05 in ♒ Aquarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 11 August 2059 at 09:12 in ♍ Virgo.

Distance to Moon 366 529 km

The Moon is 366 529 km (227 751 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 406 129 km (252 357 mi).

Moon before ascending node

10 days after descending node on 20 July 2059 at 05:06 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from South to North in ascending node on 1 August 2059 at 19:16 in ♉ Taurus.

Moon before northern standstill

7 days since the last southern standstill on 23 July 2059 at 10:35 in ♑ Capricorn when the Moon has reached South declination of ∠-26.645° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠26.681° at the point of next northern standstill on 5 August 2059 at 06:00 in ♋ Cancer.

Draconic month

24 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 8 August 2059 at 07:37 in ♌ Leo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
